Replacement Greenstar Danesmoor boiler - advice please

[Hugh Rudge]

My current Bosch Danesmoor is 20 years old and still running and burning well. It is regularly maintained and frequently requires minor parts. Obviously, it is costly to run because it is not condensing, and I expect that the parts will become hard to get at some stage. I want to replace it before it breaks permanently and before new boilers get totally banned. So I have started my research and am focussing on a new Greenstar Danesmoor.

As an additional requirement I feel that it would be best to convert the vented* house system to a pressurised system. The current Bosch Danesmoor sales info is not entirely clear what a system boiler has that a regular boiler doesn't. Does it contain it's own pressure vessel? (My daughter's new gas system boiler has an integrated PV).
*When I say "vented", my house has a header tank without a vent pipe (I kid you not). Gas has to exit via the header tank and wakes us up.
I know that a system boiler includes a pump, but my current pump is only 9 months old.

Additionally, when the current boiler goes into lockout, the controller is unhelpful with diagnosis. The service engineer has to swap out parts until it works. He tells me that some controllers provide coded info which helps the diagnosis. Does the modern Greenstar Danesmoor provide such fault indication?

Thanks

You're right - if you go for the System version it will have an expansion vessel and pump included. I think the burner on that model is a Riello - and I think it uses LEDs to indicate a fault code. Upgrading the system to pressurised one would also require you to upgrade your hot water cylinder - as your existing one is almost certainly not rated to deal with the increase in pressure.

Thanks. No problem re. hot tank. I had a Stelflow put in shortly after moving in.

I would strongly recommend that you look at other options that don't begin with a W.
Worcester are not what they were we have replaced a fair number only just out of warranty
Picture attached of a 5 year and 6 weeks old Worcester. It had been correctly installed and serviced at correct intervals.

We are Grant installers but if your boiler is below 30 kw houndsfield are worth a look.

That is shocking

Later boilers 'just out of warranty' of any make do not last as long as their predecessors. The replacement of parts such as photocells or pump coils is a fact of life with any boiler. Whilst the modern control box may give signals indicating faults to be told 'no flame detected' is not particularly helpful and still requires a technician to use his experience and common sense. If it stil lruns I'd keep it another year at least.

You have just popped my bubble. I assumed that a new one would be just as good. Don't they offer a 7 year warranty? I will take a look at the other options. Thanks.

10 years warranty is fairly common the Grant vortex pro is 10 years if it's commissioned by a Grant registered engineer.
Needs to be installed as per manufacturer instructions and serviced at correct intervals.
One of my sub contractors used to work for Worcester he regularly sub contracts to Worcester replacing oil boiler heat exchangers failed under warranty.
